Why do Sasanka(students) study even though its relative grading?

Disclaimer: Sasanka Bhagabati, here, is a fictional
character. If, from his character sketch, you draw any resemblance with a
namesake residing in A-122, that’s sheer brilliance on your part :D.

Observing is an art of making curious, obvious.

Aim

So like any other sincere student of an IIT, I have often been plagued by this innocent
question, Why the hell do we need to study? As most of us have long forgone our scholarly
pursuits, it seems even more illogical to mug for long hours before examination. Don’t you think, it would have been amazing
to score grades without messing with your sleeping schedules? And yes we all think it’s possible as grades are relative, yet due to some muggers we are all forced to bear the
plight of studying every time before the exams. So, the aim of this blog is to determine
why students study for exams when they can all manage good grades if none of
them study?

Prerequisites:

I don’t know why I have written it but may be after writing so many
practical files I am habituated to write PREREQUISITES after AIM. First of all,
to read this blog there is no prerequisite, all you need is logical sanity. I have drawn an analogy from a situation called prisoners’ dilemma used in Game Theory but
it is really basic so you don’t need to go through all that to comprehend this blog.
Moreover, it would ironic to endorse any form of study in this blog when we are discussing its purpose on the first place, isn't it?

Sample:

A group of
sleep deprived IITians who are forced to mug PowerPoint slides for their end
terms. None of them have any interest in learning the subject and they are driven solely
by the need for good grades. We assume they have similar primitive
understanding (which is enough to fetch passing marks) but different learning
abilities i.e. all of them will score same grades if none of them are studying
but if they study, everyone will score differently depending on their learning
abilities.

Grading System:

Grading System is a 10 point scale on which students’ performances
are rated with 10 being the best. However, it not an absolute scale but a
relative one so a student’s performance is measured against the performance his
classmates. So if you score well and yet others score better, you might get
poor grades and vice-versa. However, to score 10 you need to score above a
threshold marks but there are no such thresholds for any other grade i.e.
grades from 1-9 are purely relative. No grade is awarded if someone fails.

Subject:

Our Subject

Utmost discretion has been

maintained to prevent his

identity from being revealed.

Our subject, Sasanka Bhagabati, is a religious and punctual student (I
really mean it). He dedicates 8-10 hours every day for his studies. But, like many other IITians he has no interest in engineering and grades are his only
motivation. In spite of all this hard work Sasanka Bhagabati has never been the
batch topper. He is frustrated and believes that return on his investments is
not good enough. Out of desperation, he has sought professional help from the
author (who somehow holds expertise in earning without learning) on whether he should continue studying or not?

Solution:

Assumption: Everyone is driven by the selfish motive of getting better grades.

To precisely determine what the best course of action is for Sasanka, we need to make a list of all possible situations and respective outcomes. For simplicity, let us
assume that samples behave identically i.e. if one student in the sample is not
studying then the entire sample is not studying and likewise. So now there are
four possible situations: Both Sasanka and Sample are not studying, Sasanka is
studying but Sample is not, Sample is studying but Sasanka is not and both
Sasanka and Sample are studying. Now we draw a possibility matrix representing all the above mentioned situations and depicting the possible outcomes in
terms of grade of Sasanka and average grade of Sample. It is represented as (X,Y)
with X being Sasanka’s grade and Y being samples average grade.

Possibility Matrix for Sasanka

Now, when no one is studying, we assume that everyone will score same marks
which would obviously be less than the threshold thus securing a grade of 9.
Now if Sample is not studying but Sasanka is, he can cross the threshold and
secure 10. On the other hand everyone else’s grade will fall as their
performance compared to Sasanka is now poor. If the situation is reversed,
Sasanka’s grade will fall drastically as his performance compared to others is
much worse. However, it must be noted that Sample’s average is not 10 as
everyone has different reading abilities so their grades will lie in wide
spectrum with Sasanka’s grade being the lowest of all. Now, the last section is
left as (X,Y) as we can no longer predict anyone’s grades in this situation as
it would depend on their reading abilities.

Let us try to what is the favorable action in two independent situations for
Sasanka i.e. When sample is studying and when it isn't.

Case-1: Sample is not studying.

Even though (9,9) is a favorable situation for all but, since, Sasanka is
driven by the selfish motive of getting good grades he will always try to make use of this easy opportunity to
score a 10. Thus, it is evident that he should study when no one else is.

Case-2: When Sample is studying

Now, even though we can’t determine what Sasanka’s grade are going to be in the last case. But
when he was not studying he was at bottom with minimum grades so it is
self-evident that by studying Sasanka can only improve his grades not worsen it.So, once again, studying is the favored option.

Conclusion:

So, here we have come across a strange observation, popularly, known as condition
of strict dominance i.e. when one choice in a situation clearly dominates the
other choices for a person irrespective of what others involved
in the situation decide to do. Here, too, the choice of studying is always a
better choice irrespective of what others do. So, unfortunately, we are forced
upon with the conclusion that our subject Sasanka Bhagabati’s studying was
justified(and yet I am writing this blog while my end semesters are on). At the same time, this result helps you in appreciating the effectiveness of this
grading system which leaves you with no rational choice other than studying if
you seek good grades.

There are several amazing concepts in our day to day life
behind which are veiled simple explanation and ingenious thoughts. All you need
to do is observe intently, search inquisitively and you may stumble upon the
logic of life.

If experiencing the unpleasant can trigger gleeful memories of past, then that spell in past must have been extraordinarily cheerful.
When I last wrote a blog, I was still in college. Writing a blog was one of the leisure I could pursue given the luxury of time. But more importantly, writing a blog was testimony of my naive belief that an idea should always be expressed and mere expression of a thought can spark a change in itself. Such were those days. Today I am writing to pay reverence to a time when to me world still appeared to be salvable (I am not certain of it being a word, but it suited my purpose the most). "I am pissing steam"

It all started with today's fucking cold weather in Bangalore. Yes, to my surprise, it does get chilly here. Though, it is not really worrisome, but it did get me thinking about the steam pissing cold ( as Tanuj would put it) we used to have in the campus. Those were the times when I used to leave a laptop under my blanket with Call …

"For all its faults we love this city." - The city of Djinns
The thought of spending a couple weeks in Delhi in mid-April is something most people would dread and yet, I was brimming with excitement and anticipation. To me, it presented an opportunity to break away from the monotonic work culture of Bangalore and to reminisce about the old days with my college wing-mate in the city I once used to call my second home. Now, while sitting in my return flight to Bangalore, I am penning down my memoir of this trip to Delhi. Heat, Warmth and Hotheads
Summer heat was the first thing I sensed after stepping out of my flight in Delhi. This experience completely wiped out whatever tranquil effect was lingering on from the mesmerising aerial view of the city from my flight- ’ The floating island of lights in the sea of darkness' . I estimated the temperature in Delhi at the moment - validated it using the Accuweather app and registered the fact that Delhi nights were hotter than …

“We, being a secular party, believe that religious minorities deserve
reservation. – Samajwaadi Party”
If you are unable to notice the apparent irony in the aforementioned
statement, it is by no fault of yours for we have been raised, essentially, in
a society where notions of secularism are derived from political acuity and
intellectual hypocrisy. The term secular has been frequently in a skewed sense
by the government in order to justify controversial policies, political parties
to procure votes, by intellectuals to exhibit religious tolerance and
sensitivity and the revered media to denounce the so-called ‘non-secular
parties’. Various political parties and multitudes of wiseguys, for long, have
been meddling with the idea of secularism is such a way that it is being
misconstrued by the majority of commoners. For decades, policies have been amended,
minorities have been appeased and vote banks have been secured in the name of secularism.
Finally, I would like to pose the pertinent…

About Me

I believe nothing is definitive and thus, I can't really describe how I am. In actuality, how I am to X will certainly differ from how I am to Y. However, due to concurrence of opinion a majority of such X and Ys (my friends) I am forced to believe that I do possess certain traits which is witnessed by most of them. It is indisputable that I am more serious than I should be.
I am dogmatic(they all say and I always disagree, which eventually confirms their acquisition). I am weird and boring(disputable). However everything mentioned can be false as well. It depends on how much you know me..and frankly speaking you never know enough.
